The larger ovarian follicles consist of an external fibrovascular coat, connected with the surrounding stroma of the ovary by a network of blood vessels, and an internal coat, which consists of several layers of nucleated cells, called the membrana granulosa. It contains numerous granulosa cells.
Partial oophorectomy (i.e., ovarian cyst removal not involving total oophorectomy) is often used to treat milder cases of endometriosis when non-surgical hormonal treatments fail to stop cyst formation. Removal of ovarian cysts through partial oophorectomy is also used to treat extreme pelvic pain from chronic hormonal-related pelvic problems.
The cumulus oophorus (discus proligerus) is a cluster of cells that surround the oocyte both in the ovarian follicle and after ovulation. In the antral follicle, it may be regarded as an extension of the membrana granulosa. The innermost layer of these cells is the corona radiata. [1]
In medicine, Meigs's syndrome, also Meigs syndrome or Demons–Meigs syndrome, is the triad of ascites, pleural effusion, and benign ovarian tumor (ovarian fibroma, fibrothecoma, Brenner tumour, and occasionally granulosa cell tumour). [1] [2] [3] Meigs syndrome resolves after the resection of the tumor. Because the transdiaphragmatic lymphatic ...
Many cysts remain small, are followed closely by a clinician, and resolve on their own. [8] Surgery and/or drainage is performed to remove the cyst. [10] Treatment continues after the surgical removal by scheduled followups with the medical provider who looks for changes in the cyst. [8] Bartholin gland cysts often need to be drained.
If the egg fails to release from the follicle in the ovary an ovarian cyst may form. Small ovarian cysts are common in healthy women. Small ovarian cysts are common in healthy women. Some women have more follicles than usual ( polycystic ovary syndrome ), which inhibits the follicles to grow normally and this will cause cycle irregularities.
A depiction of the ovarian cycle in animals. In human adult females, the primordial follicle is composed of a single oocyte surrounded by a layer of closely associated granulosa cells. In early stages of the ovarian cycle, the developing follicle acquires a layer of connective tissue and associated blood vessels. This covering is called the theca.
Under action of an oocyte-secreted morphogenic gradient, the granulosa cells of the tertiary follicle undergo differentiation into four distinct subtypes: corona radiata, surrounding the zona pellucida; membrana, interior to the basal lamina; periantral, adjacent to the antrum and cumulus oophorus, which connects the membrana and corona radiata ...
